Discrete & Integer Data
Integrated into the Mathematica system are powerful functions for analyzing large volumes of discrete and integer data—often conveniently specified using Mathematica's uniquely flexible pattern language.
Differences successive differences
Accumulate cumulative sums
Ratios  ▪ Total  ▪ Commonest  ▪ Mean  ▪ Median
    
Union unique elements in a single list or between lists
Tally tally distinct elements, listing them with their multiplicities
BinCounts, BinLists count, list elements in a sequence of bins
    
Cases list elements matching a pattern
Count count elements matching a pattern
Position positions of elements
Sort  ▪ Split  ▪ Complement  ▪ Intersection
list/.rule replace elements according to a rule
Converting to Other Forms
ArrayRules convert to positionvalue sparse array form
FromDigits convert to numbers, polynomials, etc.
ToString convert to a string
    
ListPlot  ▪ ArrayPlot  ▪ ColorRules  ▪ ...
    
FindSequenceFunction find functional forms for integer sequences
